And Soy Protein Isolate

Soy protein isolate is a highly purified form of soy protein. It is made from soybeans that have had most of their fat and carbohydrates removed. The resulting product is typically over 90% protein by weight.

Manufacturers use soy protein isolate as a protein supplement and as a texturizer in foods. It is often added to energy bars, protein powders, and meat alternatives to boost protein content and improve texture.

Soy protein isolate is generally recognized as safe (GRAS) by the FDA for use in food. It is a complete protein, meaning it contains all the essential amino acids. JECFA has evaluated soy protein isolate and established an acceptable daily intake. Some research suggests that consuming soy protein may have benefits for heart health, but evidence is mixed.
